guys i'm trying to enter in some dedicated server and i have mw3 on pc (steam) and is it updated to 1.4 ( i can play online normally) but everytime i try to enter in a dedicated server i get this error:Server error: the server have a different version : 1.4 so WTF i must do to enter in that server? i tryed to enter in thousand of servers but i ever get this sneaky error, i have opened my router port and in game i have "NAT: open" so where's the error?

i don't know much about this.
But have you tried to use the MW3 Dedicated Tool?
So it might be what you need to launch to be able to play on dedicated servers.

well, where i can find this multiplayer server tool?

Inside the steam tools.

I will show you....
